Understanding European Motor Oil Standards

European Motor Oil Specifications Explained

It’s important to use the right motor oil for your European vehicle, but the sea of specifications can make it a challenge. AMSOIL European Car Formula finds the sweet spot of emission compatibility and complete engine protection for every application.

The European Automobile Manufacturers’ Association (ACEA) establishes lubricant standards for Europe, similar to the American Petroleum Institute (API) in the United States. ACEA recognizes that European engines differ from U.S. engines in both design and operating conditions. European OEMs often maintain their own motor oil performance specifications and play a larger role in their development than their U.S. counterparts. Volkswagen* drivers, for example, must use an oil that meets the requirements of VW’s own performance specs. The same holds for Mercedes*, BMW*, Porsche* and other European vehicles. 

Many European vehicles available in North America today feature gasoline and diesel engines with emissions systems that are highly sensitive to the SAPS content of motor oil. These advanced emissions systems require lower SAPS formulations to properly function for a long period of time. The required formulations match the exacting engine oil specifications of ACEA and European OEMs to ensure they are compatible with current emissions systems while still providing engine protection.

AMSOIL Severe Gear Synthetic Gear Lube Beats Mobil 1 & Valvoline

FOR THE ULTIMATE COLD-WEATHER PROTECTION, TRUST AMSOIL 

Some gear lubes fail to meet basic low-temperature requirements.

Mobil 1 75W-140 Gear Oil, for example, failed to meet the requirements of the industry standard*. AMSOIL SEVERE GEAR®, on the other hand, delivers 20% more cold-temperature protection than the standard requires. It delivers better cold-temperature protection than Mobil 1 and Valvoline SynPower.

*Based upon results of samples of Mobil 1 75W-140 and Valvoline SynPower 75W-140 purchased in 2018 and tested in ASTM D2983 by an independent testing facility in May 2018. Samples sent blind to eliminate bias.

Signature Series Keeps Engines Cleaner Than Other Synthetic Motor Oils

AMSOIL Signature Series

In general, the higher an oil’s TBN, the better its ability to neutralize contaminants such as combustion by-products and acidic materials. Higher TBN oils neutralize a greater amount of acidic material, which results in longer oil life and cleaner engines.

TBN levels decrease as the oil remains in service. When the level reaches a point where it can no longer protect against corrosion, the oil must be changed.

The TBN Test

The Total Base Number Test (ASTM D2896) uses a series of chemical reactions to measure the alkaline additives in a motor oil. We recognize the value of formulating motor oils with high TBN, and AMSOIL Signature Series Synthetic Motor Oil features the highest TBN of the oils tested.

AMSOIL Signature Series is fortified with a heavy treatment of detergent additive and it delivers 30% more acid neutralizing power1 than Mobil 1, and 36% more than Royal Purple, helping engines to stay cleaner, longer.

The AMSOIL Advantage

AMSOIL synthetic lubricants feature a large dose of quality additives that consistently deliver high TBN for the life of the oil. They neutralize acidic contaminants and keep them in suspension to maximize engine protection. AMSOIL lubricants use detergent and dispersant additives to significantly reduce sludge and carbon deposit formation. In the Total Base Number Test (ASTM D2896), AMSOIL Signature Series 5W-30 Synthetic Motor Oil demonstrated the highest TBN of the oils featured in the test, helping it deliver reliable protection for extended drain intervals.
